Not sure what they mean by 30% less emissions - does it mean that 70% of the carbon is burnt in the process of converting the tyre back into diesel? In which case the net emission of CO2 increases by 200%. Also I object to it being called renewable or green energy. From an emissions point of view it is better to dig a big hole and bury the tyres. Or build new houses out of them.

Burying them? All these? There is also the long term pollution of ground water to consider._________________If you think the economy is more important than the environment, try holding your breath while you count your money.
